To a/ZZ whom t 77mg/ 004067701 with the end folds 8 9, respectively. In cer- Be it known that I, HENRY LOWY, a cititain classes of paper boxes I provide the side zen ofthe United States, and a resident of the folds 7 with a top 16, having flaps 17 18 and 55 city of New York, borough of Manhattan, in a tongue 19; but it will be understood that in 5 the county and State of New York, have inother styles of boxes the top, with its flaps vented new and useful Improvements 4in and tongue, is omitted. vThe blank is creased Foldable PaperBoxes, of which the following or scored along the side and end portions is a full, clear, and exact description. thereof at a b to define the limits of the side 6o This invention relates to improvements in and end folds.

The 9o ranging the interlocking parts. Fig. 3 is a tongues 2O on the side iaps are cut from the 4o horizontal section taken through the box in material comprising the end flaps 14 15, thus its folded condition. Figs. 4 and 5 are verenabling me to produce the box-blank with tical transverse sections taken in the planes an exceedingly small amount of waste of the indicated by the dotted lines 4 4 and 5 5, restock or material. 95 spectively, of Fig. 3. The box-blank herein shown and described 45 The box-blank A is cut, stamped, or othercan be easily and quickly bent into shape to wise produced in a single piece from a sheet produce a complete box, and the several parts of paper-stock or equivalent material, said of said box are adapted to be assembled and blank being cut and scored at one operation interlocked in a way to hold them firmly in roo in the shape shown by Fig. 1. The blank place without resorting to the use of paste, 5o consists of a body portion 5, side folds 6 7, glue, or other mucilaginous material. The end folds 8 9, iiaps lO 1l 12 13, integral with side folds 6 7 are first bent upwardly along the side folds 6 7, and end flaps 14 15, integral the score-lines a, and the flaps 10 11 12 13 are then bent along the score-lines c c', so as to extend inwardly and overlap in pairs, the flaps 10 11 at one end. of the blank constituting one pair of overlapping iiaps, While the other aps 12 13 at the opposite end of the box constitute the other pair of overlapping iiaps. The tongues 2O on the flaps 10 12 extend inwardly therefrom and rest 'on the body 5, while the corresponding tongues 2O on the aps 11 13 fit beneath the lower edges of the fiaps 10 12 and also rest on the body 5, the positions of the tongues formed by the respective pairs of aps being indicated by Figs. 2 to 4, inclusive. After the flaps on the side folds shall have been properly assembled the end folds 8 9 are bent on the crease-lines b and the end aps 14 15 are bent on the crease-lines b, so as to extend over the respective pairs of aps 10 11 12 13, after which the lips 22 are manipulated to make them lit into the apertures 23 of the inwardlyextending tongues 20. The engagement of the lips 22 with the perforated tongues on the respective pairs of iiaps 10 11 12 13 interlocks the several parts of the box in a way to hold them against relative movement or displacement,'and the box will hold or retain its shape without the employment of separate fastening means.

It is evident that the top 16 when it is used may be folded over the upper portion of the box and that the iaps 17 18, along with Ithe tongue 19, may be tucked into said top of the box for the purpose of holding itself in place, the Iiaps of said top preventing the escape of material from the box, while the tongue 19 operates primarily as ameans for holding the top in place against accidental movement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A box-blank having a body portion, side and end folds, and side and end flaps each end flap having at its outer edge a series of lips; the side flaps being each of less length than the aggregate length of one end fold and end flap, and each side ap having a perforated tongue cut from a sideedge of one end yiap. y

2. A box having a body portion, side folds and flaps, and end folds and flaps; the side flaps having tongues which are cut out of theV stock of the end iiaps and are arranged to rest on the body portion; the end flaps being folded over the side flaps and provided with lips which interlock said tongues.

3. A box having a body portion, side folds, side flaps each having tongues, end iiaps, and

end flaps provided with lips; the tongue of one side ap tting beneath acompanion side iiap, and said lips having interlocking engagement individually with the tongues.

4. A box having the sides thereof provided with in wardly-foldable flaps formed with pe'rforated tongues arranged to lie inside of the box, and ends having flaps which are foldable over the side iaps and are provided with projections to interlock with said perforated tongues.

5. A box having sides provided with inwardlyfoldable liaps disposed in lapping relation, said flaps having tonguesextending into said box, one of said tongues lying below one of the flaps, and end folds having flaps foldable over the lapping side flaps, said end flaps having interlocking engagement with the tongues of the side flaps.

l In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
